USE OF AGRO-INDUSTRIAL WASTE FOR THE DEVELOPMENT OF THEOBROMA GRANDIFLORUM SEEDLINGS

Objective: The aim of this study was to evaluate the behavior of cupuaçu tree (Theobroma grandiflorum) seedlings as a function of agro-industrial waste. Method: The influence of agro-industrial waste on the development of cupuaçuzeiro seedlings was evaluated. Treatments included different proportions of organic waste (açai ash, dendê compost and cattle manure) in proportions of 5%, 10%, 15% and 20% in relation to 3 kg of soil. Finally, morphological and physiological variables were determined. Result and Conclusion: The experimental data was analyzed using analysis of variance. Significant means were then compared using the Tukey test, with a significance level of 5%. From the results obtained, it was observed that one of the agro-industrial residues has the potential to act as an alternative substrate in the production of Theobroma grandiflorum seedlings. Researchimplications: The Theobroma grandiflorum species stands out as being extremely important, since its products and by-products are widely accepted in domestic and foreign markets, as well as contributing to Agroforestry Systems. In addition, there is a need to study alternative substrates, especially those generated on a large scale, considering the need to promote proper disposal with sustainable use. Originality/value: In the current scenario, with regard to the destination and final disposal of solid waste, there is a need to look for sustainable alternatives aimed at reusing this waste, especially in agriculture. Objetivo: objetivou-se, com a realizaçâo do trabalho, avahar o comportamento de mudas de cupuaçuzeiro (Theobroma grandiflorum) em funçâo de residuos agroindustriais. Método: Avaliou-se a influencia dos residuos agroindustriais para o desenvolvimento de mudas de cupuaçuzeiro. Foram realizados tratamentos que incluíram diferentes proporçoes de residuos orgánicos (cinza de açai, composto de dende e estéreo bovino) corn proporçoes de 5%, 10%, 15% e 20% em relaçâo a quantidade de 3 kg de solo. Por fim, foram determinadas as variáveis morfológicas e fisiológicas. Resultado e conclusâo: Os dados experimentáis foram analisados por meio da análise de variancia. As medias significativas foram posteriormente comparadas utilizando o teste de Tukey, com um nivel de significancia de 5%. A partir dos resultados obtidos, observou-se que um dos residuos agroindustriais possuem potencial de atuar como substrato alternativo na produçao de mudas de Theobroma grandiflorum.
